The stock cranks on my '08 P1 leave a lot to be desired. I'd like to upgrade to another set of bmx type cranks. The current bb on the P1 is 19mm euro, I think it should be compatible with other 19mm set-ups. I'm hoping to buy just the arms and spindle.
I found these on Dan's comp. There are no spindle length options listed. What spindle length do I need? Will this set up work?

I'm open to other suggestions, looking to spend $150 or less.

to be safe, get the 6" profile spindle to go with the arms (which you can buy separately).

What problems are you having with the stock arms? I just bought a 09 p1 crmo and I'd like to know if I'm in for trouble.

They come loose almost every ride. If I had to guess it has a lot to do with design.

Buy a 6 inch spindle and you will be good. It's all compatible as long as you get a 19mm euro axle.
